Problem setting capturetarget on Canon G9

[Cedric Scott]

I'm using gphoto2 2.5.2 on Linux (Debian Jessie). My camera is a Canon G9

I can set capturetarget with gphoto using  --set-config-index but can't set it with --set-config-value

$ gphoto2 --get-config capturetarget

Label: Capture Target

Type: RADIO

Current: Internal RAM

Choice: 0 Internal RAM

Choice: 1 Memory card

I would have assumed that the default was capture to Memory Card. Now let's try setting it to Memory Card

$ gphoto2 --set-config-value "capturetarget=Memory Card"

$ gphoto2 --get-config capturetarget

Label: Capture Target

Type: RADIO

Current: Internal RAM

Choice: 0 Internal RAM

Choice: 1 Memory card

No. It's still set to Internal RAM

$ gphoto2 --set-config-value "capturetarget=Internal RAM"

$ gphoto2 --get-config capturetarget

Label: Capture Target

Type: RADIO

Current: Internal RAM

Choice: 0 Internal RAM

Choice: 1 Memory card

$ gphoto2 --set-config-index capturetarget=1

$ gphoto2 --get-config capturetarget

Label: Capture Target

Type: RADIO

Current: Memory card

Choice: 0 Internal RAM

Choice: 1 Memory card

Ah - that works

$ gphoto2 --set-config-index capturetarget=0

$ gphoto2 --get-config capturetarget

Label: Capture Target

Type: RADIO

Current: Internal RAM

Choice: 0 Internal RAM

Choice: 1 Memory card

And that works as well.

I've run the following command with debug and can send the file to anybody who's interested.

gphoto2 --debug --debug-logfile capture-target.txt \

 --get-config capturetarget \

 --set-config-value capturetarget="Memory Card" \

 --get-config capturetarget

As far as I can tell from the debug file, ghoto2 is setting capturetarget to Memory Card and is then setting it back to Internal RAM.

It would be a great help if I could use --set-config-value rather than --set-config-index and I'd love to know if this a bug or if it's caused by something I'm doing wrong.

You probably need to use the correct string, including capitalization
"Memory card" with lowercase c.

"Memory card".

Hi,

have you maybe figured out why your camera resets to internal ram? I'm having the same problem, although with a Nikon camera...

The capturetarget is stored on the computer in the HOME directory of
the user, in $HOME/.gphoto/settings

Check if this file is there and writeable.

Especially in embedded platforms this might not be the case, which
would lead to a reset back to SDRAM (the default).
